Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the production of foods, etc.
The present invention relates to a composition that improves the peelability between a food manufacturing machine, a container or a packaging material and the surface of a food, and facilitates the removal of stains derived from food that adheres to the food manufacturing machine or the container.

2. Description of the Related Art When mixing or cooking raw materials for foods or wrapping them in packaging materials after heating and processing in the production of foods, the foods themselves have an adhesive property, and therefore these raw materials or foods and their manufacturing machines, containers or There is a problem that the packaging material adheres to the packaging material and becomes difficult to remove. For this reason, a method has been adopted in which oils and fats such as lecithin, margarine, shortening, rapeseed oil, salad oil, and sesame oil, and silicone are applied to the surfaces of these machines, containers, and packaging materials.
Furthermore, a method of improving the mold release by performing a treatment such as Teflon processing is adopted.

[0003]

In the process of mixing raw materials and auxiliary raw materials in the processing of food, a part of the raw material of the food adheres to the surface of the manufacturing machine and becomes a hotbed of microorganisms. However, there is a problem in that cleaning becomes very difficult because of the strong adherence. In addition, even in the step of molding these raw materials and applying heat, the adhesion between the food and the machine or container becomes stronger due to the heat treatment, so when removing the food, the food itself loses its shape and the appearance is remarkably increased. In some cases, it will be damaged. Further, even in the packaging stage, it is often observed that a part of the food is peeled off or hardly peeled off while being attached to the surface of the packaging material due to contact with the surface of the packaging material. These points are mentioned as serious problems in producing foods, and they are regarded as problems because they significantly reduce the commercial value.

Rapeseed oil, salad oil, lecithin, sesame oil, etc., which have been conventionally used for avoiding these problems, are very viscous, and thus may be inconvenient when applied to a production line, or When sprayed in a small amount in order not to impair the flavor of food, the surface may not be covered uniformly, so food may partially adhere, while when used in large amounts to prevent it, it has the drawback of degrading flavor. . In addition, since these oils are applied to the production line and containers, they create an environment where microorganisms are likely to attach, so it can be said that there are many opportunities for secondary pollution. In the case of silicone, the peelability is relatively good, but it has a peculiar odor and has the drawback that it is very difficult to clean.
